[FIX] hw_drivers: Fix unmount of cups folder

Browse Source 
To add or modify printer the /root_bypass_ramdisks/etc/cups/ need be writeable.
And /root_bypass_ramdisks/etc/cups/ = /etc/cups/
But when we make 'sudo mount -o remount,ro /' we put the /etc/cups/ and so
/root_bypass_ramdisks/etc/cups/ folder on read-only.

After all 'read-only' command we make another command to put cups folder writeable
